The battle to become California’s next state treasurer will feature Fiona Ma, a state Board of Equalization member and former San Francisco supervisor, facing off with Republican Ron Conlon.

Ma, a 52-year-old San Francisco Democrat and a certified public accountant, received 43.2 percent of the vote in Tuesday’s primary election, with 99.1 percent of precincts partially reporting as of 7 a.m. Wednesday.

She is the front-runner to succeed State Treasurer John Chiang, who ran unsuccessfully for governor. Conlon and Republican Jack Guerrero both ran their campaigns on a relative shoestring, while Ma raised more than $1.6 million for the primary.
